Hybrid drive unit`s moment controlling method for e.g. hybrid vehicle, involves operating electrical machine with electromotive moment and determining electromotive maximal moment depending on actual parameter of energy storage

摘要

The method involves energizing an electrical machine by an energy storage and providing a positive electromotive moment that represents a total drive moment of a hybrid drive unit in combination with combustion-engined moment. The electrical machine is operated with the electromotive moment when the desired moment is larger than a combustion-optimized combustion-engined maximal moment. An electromotive maximal moment is determined depending on an actual parameter of the energy storage. Independent claims are also included for the following: (1) a hybrid drive unit including an internal combustion engine (2) a moment controller including a program algorithm for executing a method for a moment control of a hybrid drive unit.
